Thanks PP, for possibly correcting me, but you need to give more stuff to read & understand your point.
if i understand correctly, you are saying that, if i buy a 3TB SATA III EHDD, i will not get 500-600 MB/s ( actually 477-572
MiB/s ) while transferring say a 4GB file to my computer (1TB SATA III HDD) via Thunderbolt (assuming both HDDs are >50% empty & defragmented)
I am assuming that you have a point (i read your explanation & the stuff to read about the micro-stuttering of Radeon7xxx Vs. Nvidia660Ti) - but i just need to know/read more about it.
I didn't had time to explain that by mind boggling speed i meant 500-600 MB/s, since i was getting late for the trip. BTW, Seagate 3TB is unavailable & WD 3TB is available at ฿4500 from WD retail store & at ฿4460 from J.I.B (a computer parts seller WD collaborated with) at Panthip Plaza, Bangkok.
Theoretical speeds only (not common in practical cases):
SATA 3 (SATA-600) - 6000 Mbit/s or 600 MB/s
USB 3.0 ---------- 5 Gbit/s or 625 MB/s
Thunderbolt ------ 10 Gbit/s × 2 or 1,250 MB/s × 2
( 1 Gbit/s = 1,000,000,000 bit/s )
( 1 Mbit/s = 1,000,000 bit/s )
( 1 MB/s = 1,000,000 byte/s )
